A cluster model is used to calculate electron energy-loss fine structures in crystal. The multiple-scattering self-consistent-field method is employed in the ca
Let (K, M) be a linear matrix problem induced from a finite dimensional algebra Λ. Then an n×n matrix M in R(K, M) is indecomposable if and only if the number
The Beijing free electron laser (BFEL) has been employed for the first time to study the nonlinear photoconductivity characteristics of the typical infrared pho
Co/Cu/Fe nano-sized sandwich thin films have been prepared by electron beam evaporation. 5 μm×5 μm Co/Cu/Fe sandwich heterojunction was made using photolitho
